Renewable Energy Systems: Overview of Energy Use

Assessment 3: CASE STUDY

A Ford Fiesta 1.5 TDCi diesel car will travel an average of 78.5 miles for each gallon of fuel consumed on a combined cycle. With entirely motorway driving, Ford claim the fiesta can achieve 88.3mpg. [https://www.evanshalshaw.com/blog/top-10-most-economical-diesel-cars/].
The average UK mileage is 10,000 per year.
This car will consume on average;
127.4 gallons or 579.1 litres of diesel,
The equivalent of;
579.1 x 36.9x106 = 21.37 GJ or 21.37 x 277.778 = 5,935.8 kWh of energy per year.
Small cars like this represent the best way to reduce global energy consumption, but battery or hydrogen vehicles where the power is derived from renewable energy can potentially use much less energy because electric motors are potentially 90% efficient compared to the 30% of the internal combustion engine, and regenerative braking can be implemented.

Look at the types of cars being introduced that use energy potentially from renewable sources including;
Conventional vehicles running off ethanol, biodiesel, and others.
Battery and hydrogen fuel cell vehicles with power coming from solar PV or wind turbines
Hybrid vehicles
Evaluate the performance of each by considering:
Cost
Air quality
Environmental impact
Performance
Reliability
Range
Safety
Refuelling method
You should compare them with the conventional car model that uses fossil fuels for energy. You should produce a report detailing your findings. Conclude your report with a balanced assessment of the effectiveness in terms of carbon savings and economics of the new technologies that were investigated.
The report should be about 1,500 words in length (excluding diagrams and appendices) and should be structured as follows:
Title page
Contents
Overview of the problem
Assessment of the current situation
Description of proposals that may lead to improvement
An evaluation of these proposals
Planning and other issues
Conclusion
References
